Valve Cover gasket replacement DIY

JM1271 · 03-09-2017, 04:19 PM

I need some assistance, I have a 2012 335i F30, I've seen a few things on here for the E90 but nothing for the F30. For the N55 engine is there much difference in the engine design. I need a DIY for mine, damn if I'm paying a dealer 1500 to do this, doesn't seem that it would be that complicated. Any help would be appreciated.

You Tube is your friend.

I've looked on you tube, everything that I can find is for an N54, are they the same as in valve cover design. If you have any links that would help.

Just curious, how do you know your gasket needs replacing?

It should be very similar to the below link:

While the E90 N55 and F30 N55 are different, I would not think there would be anything significant to worry about between the two with a valve cover replacement.

I don't think an N54 guide would work as there are several significant differences (re-designed PVC system, different injectors, added Valvetronic, etc).

While it appears much more involved than I expected for a valve cover (mostly due to direct injection), nothing about the job looks too difficult for a novice amateur mechanic.

I'm going by what the dealer said, just had the fuel pump done for a recall, they told me oil filter housing gasket and valve cover gasket have leaks, I can see where the OFH has a leak, that problem has been taken care of, not a tough task but that bolt on the bottom is a the hardest part.

Thanks for the link, I'll dig into it, the only thing that seems like a pain is just taking all the fuel lines and fuel rail off, and I know there's a few plastic pieces to be aware of when taking off as to not break them, thinking it'll take around 3-4 hours at most. Will keep you informed.

If you go to a trusted independent shop you can have it done for a lot less. Another alternative would be to go to REALOEM website and see how everything fits together.

Or you can get a Bentley's manual for the F-30. They are "priceless" for doing your own work.

If you get ISTAD which Bentley is based on, it's free.

JM1271 · 01-06-2018, 10:49 AM

Where can I find the ISTAD?

I cannot thank you enough. Lol

I've been looking for this for quite some time.

Just make sure you order fresh bolts for any that have a blue marking on them. Torque them correctly. I think the correct torque is listed on the new tis link posted above.

Nice opportunity to get in there and wallnut blast while you are at it!
